Security Engineer
Job Description & Overview
Someone’s got to stop people from leaving S3 buckets open to the world. That someone could be you.
We need a security engineer who cares about keeping things locked down, not just ticking boxes on a spreadsheet. You’ll work across cloud environments, CI/CD pipelines, and application security for our clients, finding the holes before someone else does. If you’ve ever lost sleep over a misconfigured security group, you’ll fit right in.
What you’ll do
- Implement security controls across AWS environments
- Configure and manage security scanning tools in CI/CD pipelines
- Review infrastructure as code for security misconfigurations
- Support clients with Cyber Essentials and compliance requirements
- Monitor and respond to security alerts and incidents
- Write security documentation and policies
- Contribute to internal security standards and playbooks
What we’re looking for
- 2+ years of security engineering or DevSecOps experience
- Knowledge of AWS security fundamentals (IAM, Security Groups, KMS, CloudTrail)
- Experience with vulnerability scanning tools (Trivy, Snyk, or similar)
- Understanding of network security (firewalls, TLS, VPNs)
- Familiarity with at least one scripting language (Python, Bash, or Go)
Nice to have
- Container security experience (Docker, Kubernetes)
- Infrastructure as Code knowledge (Terraform, Pulumi)
- Familiarity with compliance frameworks (SOC2, ISO 27001, Cyber Essentials)
- Security certifications (CompTIA Security+, AWS Security Specialty)
- Bug bounty or CTF participation
What we won’t ask you to do
- Write a 40-page risk assessment that nobody reads
- Rubber-stamp insecure designs because someone senior said so
- Sit through compliance theatre. We do real security here
- Complete a take-home test the size of a dissertation
